Imaging system for reading target with multiple symbols

摘要

An imaging system for acquiring images of multiple indicia, such as symbols and non-symbols, on a target, such as a label, comprises a solid-state imager having an array of image sensors for capturing light from the indicia on the target over a field of view, and a controller having a stored template that identifies details of the indicia on the target, for controlling the imager to capture the light from the indicia based on the details identified by the template.

1. An imaging system for acquiring images of multiple indicia on a target, comprising:
a solid-state imager having an array of image sensors for capturing light from the indicia on the target over a field of view to form a target image; a controller having a stored template that identifies details of the indicia on the target, for controlling the imager to capture the light from the indicia based on the details identified by the template; wherein the target is a label, wherein the indicia includes at least one of a one-dimensional symbol and a two-dimensional symbol applied on the label, and wherein the template identifies a position coordinate of at least one position of at least one symbol in a coordinate frame fixed on the label for determining the position of the at least one symbol in the target image if the position of any point on the label is known in the target image; and wherein the template is stored by having the imager capture light from a unique programming symbol operative for programming the controller to store the template that identifies at least a type of each symbol and identifies the position coordinate of at least one position of the at least one symbol.
